NASA releases JWST image M77

NASA released a new James Webb Space Telescope image of galaxy M77 on Wednesday, highlighting the bright core of a nearby active galaxy in an observation dated May 7. The agency said the glow at the center comes from gas being pulled by the gravity of the galaxy’s central black hole into a tight, fast orbit, where it heats up and emits large amounts of radiation. NASA captioned the image “Beacon of Light,” and published it through its image and Webb mission pages. ### What exactly is NASA showing in the new M77 image? The May 7, 2026, Webb image shows the heart of M77 shining intensely against the broader structure of the galaxy. NASA said the central brightness is tied to material falling under the influence of the galaxy’s active core, rather than to ordinary starlight alone. NASA said the gas is being pulled by the strong gravity of the central black hole into a “tight and rapid orbit around it.” As that gas moves, it heats up and releases what the agency described as tremendous radiation, producing the bright central glow visible in the image.

(nasa.gov) NASA said the bright lines extending from the center are diffraction spikes, an optical effect created by the telescope itself. The agency said those spikes are not a physical feature of M77. The clarification matters because Webb images often combine real astronomical structure with instrument effects that appear around very bright sources. (nasa.gov) In this case, NASA’s caption distinguishes the galaxy’s luminous core from the star-like spikes produced by the observatory’s optics. ### What makes M77 the kind of target Webb would study? (nasa.gov) M77 is presented by NASA here as a galaxy with an active center powered by a supermassive black hole. That places it in the class of galaxies astronomers use to study how black holes interact with surrounding gas and dust. NASA’s description of the image focuses on the motion and heating of gas near the center. (nasa.gov) The Webb Space Telescope is NASA’s flagship infrared observatory, and its mission page says it is designed to study galaxies, black holes and other distant cosmic structures with high sensitivity. That makes active galactic centers like M77 a natural fit for Webb imaging and follow-up science. ### When did NASA publish it, and how was it picked up elsewhere? (nasa.gov) NASA’s image article was published this week, with search results showing it appeared two days before May 20 and was listed on NASA’s recent Webb and agency news pages. The item is titled “Beacon of Light.” Space.com separately featured the same M77 view as its “space photo of the day” for May 19, 2026. (science.nasa.gov) Its listing described the galaxy as looking “truly out-of-this-world” in the new Webb image. ### Where can readers expect to find the image next? NASA’s Webb mission page and NASA Science news listings are carrying the “Beacon of Light” image entry alongside other recent Webb updates. (nasa.gov) Readers looking for the full caption and image context can find it through those NASA pages, while Space.com’s May 19 archive carries the secondary feature presentation.
